Find an equation for the line with the given properties. Express your answer using either the general form or the slope-interce

Vladimir [108]

Answer:

y = 7x

Step-by-step explanation:

Complete question:

Find an equation for the line with the given properties. Parallel to the line 7x - y = -7; containing the point (0,0)

The equation of a line in point-slope form is expressed as;

y - y0 = m(x-x0)

(x0, y0) = (0,0)

Given the equation of the line as 7x - y = -7;

Rewrite and get the slope

-y = -7x - 7

y = 7x+7

Get the slope

mx = 7x

m = 7

Substitute into the equation

y - 0 = 7(x - 0)

y = 7x

Hence the required equation is y = 7x

Write the equation of the linear relationship in slope-intercept form, using decimals as needed.

masha68 [24]

Answer:

$y=0.95x+2.5$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take the points

(0,2.5) and (100,97.5)

substitute in the formula

$m=\frac{97.5-2.5}{100-0}$

$m=\frac{95}{100}$

$m=0.95$

Find the y-intercept b

we have

$m=0.95$

$point\ (0,2.5)$

substitute i the linear equation $y=mx+b$

$2.5=0.95(0)+b$

solve for b

$b=2.5$

Note It was not necessary to calculate the value of b because the value is given in the table

Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))

The linear equation is

$y=0.95x+2.5$
